A bar 34, carried by a sprocket chain 35, delivers a. closing nop 4 which is a prolongation of the want sharp blow to the tube from beneath. After a '2 is folded over onto the seam wou and posted bag section is severedV from the tube and at the thereto. The seam'is shown at l. 'I'he top of the instant the pinch bars free it, the severed bag bag is formed into two aps l and 8. These may section is pulled forwardly by scoring devices 3l, be rectilinear in shape but preferably they are which devices make the score line Il. The bag 55 then passes to the usual cylinders 88 which fold and paste the bottom.

The upper cylinder is provided with the usual paste bar 39 which receives paste from a roller 4|] rotating the paste supply vessel 4|, all of these parts being of the usual construction and found in an ordinary bag machine. The lower cylinder 38 carries the usual clamp 42 with which coopcrates the tucker blade 43 by which the bag bottom is folded. The finished bag then passes to the usual delivery mechanism indicated generally by 44. f

When the web is passing over the roller 20 a die 46 carried by the shaft 41 suitably driven from the lower pinch bar shaft 33 makes an incision in the web, said incision eventually forming the notch I2, Figures 1 and 2. The incision is also indicated as I2 in Figure 5. The bag, after being severed by the striker bar 34 and before the bottom is folded by the cylinders 88 has the appearance depicted at the left, Figure 5. It will be noted that the lower serrated edge 48 of the seam wall is offset from the lower wall so that when the tube section is folded along the line a-a, Figure 5, a portion of the seam wall is included within the fold. This gives a reenforced bottom which is peculiar to a bag as distinguished from an envelope. The line of paste applied by the bar 39 is indicated at 49, Figure 5.

It is to be understood, of course, that the timing of the various parts of the machine is such that the score line I 0 is made at the proper place.

After the bag tube section has passed the cylinders 88, it has the appearance shown in Figure 4.

In order, however, to produce the bag shown in Figure. 1, further operations are necessary. These consist in cutting the bag tube transversely along a line b-b which is within the serrations 50, Figure 4. This operation may be performed with an ordinary paper cutter. The edges of the Y the cuts c-c are made may, of course, be varied as desired.

Where the two fiaps 6 and 8 are of equal length then it is convenient to provide the notch I2 in one of these aps for convenience in opening the bag mouth. The incisions which create these notches, each of which is made by the die 46, are at bag length intervals apart and the timing may be such that when the tube is severed along the line 50, Figure 5, such line of severance will be just above the ends of the incision. This position of the incision prevents a tab appearing at the end of the flap of the finished bag. While this necessitates av trifle more waste of paper when the bag is cut off along the line b-b, Figure 4, the finished bag has a better appearance.

When the flaps are not required to be of equal length, the cuts along the line b-b may be dispensed with, only the cuts c-c being made.

From the foregoing it will be seen that I have produced a bag which is admirably adapted for the use for which it is intended but which may be manufactured at low cost.

What-is claimed is:-

1. An inspectable mailing package comprising a receptacle of flexible material containing a magazine, booklet or the like with one of the free edges thereof facing the mouth of the receptacle, the two edges of the mouth each having a flap extending inwardly and interleaved within the leaves of the magazine, booklet or the like, the relative size of the receptacle as compared with the contents being such that the distance between the ends of the inturned flaps and the bottom of the receptacle is less than the corresponding dimension of the magazine, booklet or the like.

in claim 1, a receptacle of ilexible material having each edge of its mouth provided with a tapered flap, said aps being proportioned and dimentioned to interleave and interlock with the contents of the receptacle.
